Admin pages error "not unique table/alias:"

Admin pages error "not unique table/alias:"

I have created admin pages with Data Assist Wizard (Data Bridge 1.1.3). On hitting 'submit' on the insert and update pages I get the error "not unique table/alias:member_data". Attempting to preview Details, Search and Results pages gives the same result. I have not altered anything - the pages are exactly as generated by the wizard.

Offending pages attached; I don't know enough about functions to find the problem - help please!
